JavaScript Regex Challenge

Hey there, I am doing a regex challenge on this site: https://beta.freecodecamp.com/en/challenges/regular-expressions/restrict-possible-usernames.

I have taken my regex and put it into this site and all the parameters pass: https://regex101.com/r/fqeFDT/1.

If I have made an error can someone please point it out? I am failing the 1st and 4th check on freeCodeCamp.

And here is my code:

let username = "JackOfAllTrades";
let userCheck = /^[a-z]{2}([a-z]+)?(\d+)?$/gi; // Change this line
let result = userCheck.test(username);

Your regex is complicated, i did this challange in 5 min. I believe the best advice here is just start over, try diffrent way, remember to keep this simple. Use regex101.com reference as guide.

I'll restart, but do you have any idea why it seems to work fine on regex101.com? It passes all the parameters there.

Your solution probably doesnt work probably because due challange interpreter limitation because it works in browser console and regex101.com. You could remove /g and you will pass it.
